Microsoft Teams hangs at the start and won't load

yesterday I was still able to use Microsoft teams Desktop version in my PC. But today when I will start Teams, it just won't load, it stucks at the startup screen, saying loading and then it doesn't respond at all.

Here are some of the things I've tried so far but still haven't solve the problem:

1. Run Task manager, then end task microsoft teams and then run teams again
2. Clear the cache by deleting files inside the %appdata%\Microsoft\Teams folder
3. Uninstall Teams from add/remove programs and then download from the latest version from Microsoft Teams site.
4. Run Teams in compatibility mode, I tried for Windows 7, Windows 8 but all doesn't work
5. Checked the firewall, and it has microsoft teams rules inside with all profiles supported
6. turned off antivirus, in case this might be the one causing problems

I had tried all of these but still Teams still doesn't open. I am running Windows 10 (64 bit) and my processor is an Intel i5-3470 3.2 ghz. Btw, I had tried to download and install he latest version of teams in another computer, and it is working fine, so this problem is only isolated in my personal PC.

The one I haven't tried is to reinstall Windows but I don't want to go to that extend since I have lots of important programs and files in this PC. Anybody can offer an advice, tips on how I can make Teams run in my PC without problems? Thank you.
